The playfield begins with a bordered safe area and an open interior containing moving enemies. The player moves along claimed territory, then enters the open region to draw a temporary line back to a border or completed section.

When the line closes an area, that space becomes claimed and the remaining open region shrinks. A round is cleared by reaching its required territory percentage. Touching an enemy, or allowing an enemy to hit the unfinished trail, costs a life; later stages generally increase pressure through faster or more numerous hazards.

The central decision is whether to make a short, safe capture or attempt a larger cut that exposes the player for longer.

Start with small captures near the border to reduce the open area without leaving a long exposed trail.

Watch enemy paths before entering open space. Prefer cuts that place the new boundary between hazards and the remaining playfield, and avoid starting a move when an enemy is already approaching the intended line.

Use the edges to reposition safely, then take larger claims only when the route and enemy timing are clear.
